HAL Exoskeleton Lower Limb for the treatment of physical functions in rehabilitation.

HAL for Medical Use - Lower Limb Type is a medical device for the treatment of people with lower limb disorders. The product, which has been CE marked [CE 0197], complies with the requirements of the Medical Device Directives in the EU.

This product is designed to create a pathway for signals to reach the muscles to elicit a meaningful response through movement. This movement can be felt by the wearer and their brain, closing a signal loop that is important for inducing neuroplasticity, which is necessary for healthy motor function. Various product adaptations are also available to medical professionals to help the wearer achieve their intended movements more easily or work on correcting abnormal signals through specific therapeutic exercises that go beyond walking.

HAL for Medical Use - Lower Limb Type, is approved in the EU as a medical device for patients with symptom complex of musculoskeletal walking impairment [= MADS], such as spinal cord injury, traumatic brain injury, cerebrovascular disease and other diseases of the brain and neuromuscular systems

Elements of this product such as leg lengths, hip widths, and foot sizes can be precisely adjusted to fit all individuals, allowing for comfortable and effective treatment.

Like all other HAL systems, this product can be controlled by the wearer's intention to move. The product's non-invasive sensors can detect weak "bioelectric signals" that reflect the wearer's intention on the surface of the skin. Importantly, this unique system enables even patients with movement difficulties to perform the desired movements with their voluntary commands.

The product provides both the wearer and their healthcare provider with unique insight into the signal patterns generated by the wearer and important information such as the center of balance and phases of the gait cycle. This information helps shape the treatment course, which aims to maximize neuroplasticity and ultimately achieve greater independence.

An exoskeleton is attached to the outside of the body and provides the wearer with additional functional support. The exoskeletons used in the WALK AGAIN Center from the Japanese manufacturer Cyberdyne are made of particularly lightweight yet stable plastic and are known as Hybrid Assistive Limb or HAL® for short.

The robotic suit HAL® is the only approved system of its kind that captures the electrical signals from the brain via the skin surface of the lower extremities and provides motorized support. The movement is thus a controlled activity consciously desired by the patient. The positive feedback is sent back from the muscles to the brain. During the rehabilitation phase with HAL® therapy, the muscles are built up, the gait pattern improves significantly, becomes safer and walking aids can be reduced.
